Point
- 1. Apply 2.40 V between BATT+ and BATT-.
2. Confirm that there is no flashing of Battery Icon.
3. Apply 2.25 V ± 0.08 V between BATT+ and BATT-.
4. Confirm that there is flashing of Battery Icon.
CKM 1. Apply 2.6 V between BATT+ and BATT- with DC power.
2. Input Command "SFR", then you can confirm the current value.
3. Check X'tal Frequency. (13.824 MHz ± 15 Hz).
4. If the frequency is not 13.824 MHz ± 15 Hz, adjust the frequency of CLK exe-
cuting the command "SFR xx xx (where xx is the value)" so that the reading of
the frequency counter is 13.824 MHz ± 15 Hz.
Note:
Clear the registered information for CS before measurement, because the Fre-
quency will not possibly get stable due to the registered information.
Pressing the button of "3" "5" "7" "#" clears the registration.
Register to it on CS after measurement.
- Remove the Antenna before starting step from 1 to 4.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
• Test mode: PP
• RFPI: 0102030405
• Traffic Carrier: 5
• Traffic Slot: 4
• Mode: Loopback
• RF LEVEL = -70 dBm
• PACKET: PP32Z
2. Execute the command "TST 01 02 03 04 05".
3. Initiate connection from DECT tester.
4. Confirm that the NTP value at ANT is 19 dBm ~ 25 dBm.
- Follow steps 1 to 3 of (H).
4.Confirm that the B-Field Modulation is -340±30/ +340±30 kHz/div & Modu-
lated width
- Follow steps 1 to 3 of (H).
4.Confirm that the frequency Offset is < ± 15 kHz.
- Follow steps 1 to 3 of (H).
4.Confirm that the frequency Drift is < ± 20 kHz/ms.
- Follow steps 1 to 3 of (H).
4.Set DECT tester power to -88 dBm.
5.Confirm that the BER is < 1000 ppm.
Procedure
660 kHz using data type Fig 31.
